The way to do it is to take the criteria I have listed above and have a program automatically query it.
But I'm not sure I would trust a toolbar that would query whois for me then algorithmically score the ownership information on a 1-10 basis then fold that into the score for backlinks etc... and generate a number from one to ten. This kind of information I would like to view for myself.
One way to automate the process is to take the criteria I listed then generate the results in a one page report.
But more importantly, does anyone have additional criteria to add? I'm looking for metrics. There are others metrics for judging a link partner that I have left out. So let's have them!
